Do you know what what the existing git.el is? Try something like
  find /usr -name git.el | xargs -r ls -l
for example.

As far as I can tell it was created by a previous version of the git
package (possibly from the git ppa?), the link (and another that
caused almost the same failure) was already pointing to the same
place.

On my own system I fixed the issue by removing the two links (git.el
and git-blame.el) before re-running dpkg.

I've prepared a version of the git package that changes ln -s to ln
-sf in the relevant script to work around the error, but I don't know
if that's a good way to solve the issue, or if it might cause any
other problems, so I haven't uploaded it anywhere yet (also noone else
has reported or confirmed it so maybe it was just my system in the
first place...)

Well, in any case I can confirm and reproduce this issue as of git 1:1.7.4.1-1 by either

a) Have an Ubuntu 10.10 system with both emacs and git installed, and then upgrade to Ubuntu 11.04
b) Have an Ubuntu 11.04 system where git and emacs is installed at the same time. It doesn't matter whatever emacsen-common is installed beforehand or not.

This is fixed in the upcoming Debian upload of 1.7.4.1-2.

Fixed git is currently in Debian NEW queue. Once it hits sid, we'll sync it. Thanks Anders!
